The nurse is caring for a newborn receiving an exchange transfusion for hemolytic disease. Assessment of the newborn reveals slight respiratory distress and tachycardia. Which should the nurse's first action be?

Correct Answer: B

Rationale: Slight respiratory distress and tachycardia in a newborn during an exchange transfusion may indicate a possible transfusion reaction or overload. The first action the nurse should take is to stop the transfusion to prevent any further complications and assess the newborn's condition. After stopping the transfusion, the nurse can then take appropriate steps such as notifying the practitioner, administering medications, or providing supportive care as needed.

Correct Answer: C

Rationale: The most appropriate nursing action when an 8-year-old girl asks how the blood pressure apparatus works is to explain in simple terms how it works. Children are curious by nature and providing a simple explanation in a language they can understand helps satisfy their curiosity and also promotes their understanding. By explaining how the blood pressure apparatus works, the nurse can educate the child about a common medical device and reduce any anxiety or fear the child may have about it. This approach encourages the child to feel more comfortable and engaged in their healthcare experience.

Correct Answer: B

Rationale: A tympanic membrane sensor or tympanic thermometer is the best option for determining the temperature of a preterm infant under a radiant heater. Tympanic thermometers are quick and non-invasive, making them ideal for use in neonatal care. They provide accurate readings by measuring the infrared heat waves coming from the eardrum. This method is preferred over other options like axillary sensors, rectal mercury thermometers, and rectal electronic thermometers, which may not be as efficient or suitable for use with preterm infants.

Correct Answer: C

Rationale: A ventricular septal defect (VSD) is a congenital heart defect characterized by a hole in the septum that separates the heart's two lower chambers (ventricles). When assessing a child with an unrepaired VSD, the nurse would expect to hear a murmur. The murmur is typically described as a harsh, holosystolic (pansystolic) murmur, best heard at the left lower sternal border. This murmur occurs due to the turbulent blood flow across the defect during systole. It is important for the nurse to recognize this characteristic murmur associated with a VSD to facilitate appropriate management and follow-up care for the child.

Correct Answer: D

Rationale: The correct knowledge that the nurse's response should be based on is that it is acceptable to encourage head control and turning over. At 3 months of age, encouraging the infant to be prone while awake can help promote the development of head control, neck strength, and eventually facilitate the ability to turn over. This practice is considered safe and beneficial for infants within the appropriate age range, as long as the infant is supervised during the awake period. It is important to promote safe sleep practices for infants to reduce the risk of Sudden Infant Death Syndrome (SIDS), but allowing supervised tummy time for an awake infant is beneficial for their motor development.
